In the cleaning unit, the cleaning brush plays a very important role. The wafer needs to be cleaned by the combined action of the cleaning brush and chemical agents to remove particles, residues and other contaminants from the surface and back of the wafer.
[0003] Cleaning brushes are typically made from PVA (polyvinyl alcohol) and crosslinking agents through an acetal reaction under an acidic catalyst. They are relatively soft and porous. However, most cleaning brushes are packaged and stored in plastic bags. When stacked, the brushes and plastic bags are squeezed together by external force. In hot weather, the contact surfaces of the brushes and plastic bags will stick together, and forcibly separating them will cause damage to the surface of the brushes, thus affecting the appearance of the cleaning brushes and the user experience.
[0004] Therefore, in order to solve the above problems, a magnetic suction-type convenient cleaning brush is proposed. Utility Model Content
[0005] The purpose of this utility model is to provide a magnetic convenient cleaning brush to solve the problem mentioned in the background art that most of the cleaning brushes produced in the prior art are packaged and stored in plastic bags.

In hot weather, the contact surfaces of the cleaning brush and the plastic bag will stick to each other. When forcibly separated, the surface of the cleaning brush will be damaged, which will affect the appearance of the cleaning brush product and affect the user experience.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a magnetic suction-type convenient cleaning brush, comprising: a brush body;
[0007] A protective structure is installed on the outer side of the brush body. The protective structure includes a first protective cylinder, which is sleeved on the outer left end of the brush body. A transparent window is provided on the surface of the first protective cylinder. A second protective cylinder is threaded to the right end of the first protective cylinder. Friction grooves are formed on the far ends of the first and second protective cylinders. A fixing block is fixedly installed on the inner wall of both the first and second protective cylinders. A sliding groove is formed on the inner wall of the fixing block. A movable block is movably installed on the inner side of the fixing block. A slider is integrally formed on the outer wall of the movable block. A damping spring is fixedly connected to one side wall of the movable block. A magnetic block is adhered to the other side wall of the movable block.

[0012] Preferably, the left and right ends of the brush body are respectively inserted into the movable blocks in the first and second protective cylinders, and the magnetic block is magnetically connected to the end of the brush body.
[0013] Compared with the prior art, the beneficial effects of this utility model are: by setting fixed blocks and movable blocks, the two ends of the brush body can be supported and fixed, so that the brush body is suspended inside the first protective cylinder and the slider, keeping the part of the brush body used for cleaning from contacting the protective structure, thereby avoiding the adhesion between the brush body and the protective structure, ensuring proper storage of the brush body and extending the life of the brush body.
[0014] This utility model features a protective structure. In use, one end of the brush body is inserted into the inside of the first protective cylinder, where it is also inserted into the movable block. A magnetic block adheres to the brush body, magnetically attracting it to fix one end of the brush body inside the first protective cylinder. A second protective cylinder is then fitted over the other end of the brush body. Rotating the second protective cylinder connects it to the first protective cylinder via a thread, and the other end of the brush body is inserted into the movable block inside the second protective cylinder, leaving the middle of the brush body suspended. This allows the protective structure to... The parts of the brush body used for cleaning are not in direct contact with each other, thus avoiding adhesion between the brush body and the protective structure, ensuring proper storage of the brush body and extending its lifespan. At the same time, the movable block can move within the fixed block through the cooperation of the slider and the slide groove, and the distance between the two sets of movable blocks can be adjusted to accommodate the installation needs of brush bodies of different lengths, improving the practicality of the device. Furthermore, when the device vibrates, the damping spring can slow down the movement of the movable block inside the fixed block, thereby preventing breakage at the connection between the brush body and the protective structure, which would affect its use.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Please see Figures 1-4 This utility model provides an embodiment of a magnetic suction-type convenient cleaning brush:
[0022] The brush body 1 used in this application is a product that can be purchased directly on the market. Its principle and connection method are existing technologies well known to those skilled in the art, so they will not be described in detail here.
[0023] A magnetic suction-type convenient cleaning brush includes: a brush body 1;
[0024] A protective structure 2 is installed on the outer side of the brush body 1. The protective structure 2 includes a first protective cylinder 21, which is sleeved on the outer side of the left end of the brush body 1. A transparent window 22 is provided on the surface of the first protective cylinder 21. A second protective cylinder 23 is threadedly connected to the right end of the first protective cylinder 21. Friction grooves 24 are formed on the distal ends of the first protective cylinder 21 and the second protective cylinder 23. Fixing blocks 25 are fixedly installed on the inner walls of both the first protective cylinder 21 and the second protective cylinder 23. A sliding groove 26 is formed on the inner wall of the fixing block 25. A movable block 27 is movably installed on the inner side of the fixing block 25. A slider 28 is integrally formed on the outer wall of the movable block 27. A damping spring 29 is fixedly connected to one side wall of the movable block 27, and a magnetic block 210 is adhered to the other side wall of the movable block 27. By setting the fixed block 25 and the movable block 27, the two ends of the brush body 1 can be supported and fixed, so that the brush body 1 is suspended inside the first protective cylinder 21 and the slider 28, keeping the part of the brush body 1 used for cleaning from contacting the protective structure 2, thereby avoiding the adhesion between the brush body 1 and the protective structure 2, ensuring proper storage of the brush body 1, and extending the life of the brush body 1.
[0025] Furthermore, the transparent window 22 is used to observe the brush body 1 inside the first protective cylinder 21 and the second protective cylinder 23. The user can see the pattern of the brush body 1 without opening the protective structure 2, so as to make a distinction.
[0026] Furthermore, the second protective cylinder 23 is fitted onto the outer right end of the brush body 1, and the first protective cylinder 21, together with the second protective cylinder 23, can shield and protect the brush body 1 from both sides.
[0027] Furthermore, the outer wall of the movable block 27 is in contact with the inner wall of the fixed block 25, and the slider 28 is slidably installed inside the slide groove 26. The slide groove 26, together with the slider 28, guides and limits the movement of the movable block 27 inside the fixed block 25, so that the brush body 1 can only move along the length direction of the protective structure 2, thereby avoiding contact between the brush body 1 and the protective structure 2.
[0028] Furthermore, one end of the damping spring 29 is fixedly connected to the inner wall of the first protective cylinder 21 and the second protective cylinder 23. The damping spring 29 provides power for the magnetic block 210 to adhere to the brush body 1, preventing the brush body 1 from detaching from the movable block 27.

The magnetic block 210 is magnetically connected to the end of the brush body 1. The magnetic block 210 provides guidance for the brush body 1 to be inserted into the movable block 27 and ensures the connection stability between the brush body 1 and the protective structure 2.
[0030] Working principle: When in use, one end of the brush body 1 is inserted into the inside of the first protective cylinder 21. The brush body 1 is inserted into the inside of the movable block 27, and the magnetic block 210 is attached to the brush body 1. The magnetic block 210 can magnetically attract the brush body 1 to fix one end of the brush body 1 inside the first protective cylinder 21. The second protective cylinder 23 is sleeved on the outside of the other end of the brush body 1. By rotating the second protective cylinder 23, the second protective cylinder 23 can be threadedly connected to the first protective cylinder 21. The other end of the brush body 1 is inserted into the movable block 27 inside the second protective cylinder 23, so that the middle part of the brush body 1 is suspended. This prevents direct contact between the protective structure 2 and the cleaning part of the brush body 1, thereby avoiding adhesion between the brush body 1 and the protective structure 2, ensuring proper storage of the brush body 1, and extending the life of the brush body 1.
[0031] Meanwhile, the movable block 27 can move within the fixed block 25 through the cooperation of the slider 28 and the groove 26, and the distance between the two sets of movable blocks 27 can be adjusted to adapt to the installation requirements of brush bodies 1 of different lengths, thus improving the practicality of the device. When the device vibrates, the damping spring 29 can slow down the movement of the movable block 27 inside the fixed block 25, thereby preventing the connection between the brush body 1 and the protective structure 2 from breaking and affecting its use.
